RISHI Sunak has expressed his concerns at police revealing personal information about missing Nicola Bulley.
The PM added his name to a growing list of MPs and senior police figures who have questioned Lancashire Police.
The force has come under fire for divulging private details about Nicola that made her a high-risk missing person.
Rishi said he was "concerned that private information was put into the public domain".
He added: "I'm pleased that the police are looking at how that happened in the investigation.
"Obviously my thoughts are with Nicola's friends and family and the focus must now be on continuing to try and find her."
